IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. l 8 1,245, dated August22, 1876; application filed May 11, 1876.

To all whom it may concern: Y

Be it known that I, CLEMENT L. CARTER, of Union city, Randolph county,and State of Indiana,have invented certain Improvements in Cultivators,of which the following is'a specification:

The object of this invention is to construct a cultivator that will becompletely under the control of the operator, and will plow to the endof the row and be easily managed.

My invention consists in constructing a cultivator that is complete inall its parts, and without beams or handles, simple, and durable, theaccompanying drawing forming part of this specification.

Figure 1 represents a side elevated view of my cultivator; Fig. 2, aplan view of the frame M, to which the wheels are attached, theconnecting-bars f and the tongue t, with the crossbars h and j and theaxles c; Fig. 3, the footlevers d Fig. 4, the rock-shaft g, with thedouble cranks a a and m m. 1

In the construction of my cultivator I us the ordinary double tongue,separating the rear end to about three feet. This, with the cross-bars hand j, forms the rigid frame-work that supports the plows. w torepresent the wheels; M, the wheel-frame; e, the axles; a, the outsidestandards; I), the center shovels; H, the upper ends of the centerstandards; 1, the lever used in lifting the plows; r, the handlever formoving the center standards; 0, the rods connecting center standards Hto the lever 1",- 0, the swinging braces that prevent the centerstandards H from being drawn backward; f, the bars connecting the wheelswith the frame M to the tongue; 6, braces to support the outsidestandards; d, the foot-levers; t, the tongue; q, the elongation of theright standard a. The outside standards a are bolted to the rear ends ofthetongue, supported by the braces 2', they being secured by bolts nearthe lower ends of the standards a; One, passing forward and upward, isbolted to the tongue; the other, passing upward, is bolted to thecross-bar h, this arrangement making the standards a perfectly rigid.The center standards H pass through mortises in the bar h. Bolts passingthrough the bar It and the standards H hold the standards in place. Theswinging braces 0, being fastened near the lower ends of the standards Hand to the tongue t, will permit them to swing to the right or left withease. The foot-levers d are bent somewhat in the form of a sharp elbow,turning on a hinge or pivot at the angle, and supported by the outsidestandards a. One arm of each lever d has a stirrup riveted to it for thefoot, the other end being attached to the center standards H by hingesnear their lower extremities, and, as the standards H are free to moveto the right or left, it will be seen (the feet being in the stirrups)that, by pushing the feet back and forth, the standards H will receive aswinging motion to the right or left, the object of which is to enablethe operator to guide the plows b and throw them around the plants,should they not be in line. The lever 1' is attached to the standards Hby the rods 0, the elongation of the right standard'a forming thefulcrum for the lever r at q. The lever 1', being moved to the right orleft, will give the standards H a corresponding motion. Thus it will beseen that the foot-levers d and the lever T will give the standards Hthe same motion. The lever "r is for use when the operator is walking.

The center shovels b are intended to be used in cultivating smallplants, the lower half of the shovel being the same size and shape of anordinary cultivator-shovel, and the upper half out from each side,leaving the center about two inches wide; and, as the wide part of theshovel b will run some inches under the ground, it will be seen that itwill loosen the ground, and yet throw but little dirt on the smallplants. The rock-shaft g is a bar of the proper length to reach acrossthe rear ends of the tongue, and bent at each end to form the cranks na. It is also perforated at the proper width for staples, by means ofwhich it is fastened to the tongue. The lever l is also rigidly attachedto the rock-shaftg. The cranks a n are attached tothe cranks m m, andthey to the connecting-bars f, a short distance from the axles e, theconnecting-barsf being connected to the tongue some three feet from theaxles e.

I make a rigid frame for the wheels by bolting' two pairs of timberstogether. I connect these together by bolting a board some four feetlong at right angles with the timbers.

This forms the frame M, to which the axles e and the connecting-barsfaresecurelybolted. It will readily be seen that the frame M thatconnects the wheels n; is independent of the frame formed by the tongueand the cross-bars h and j, to which the plows are attached, the onlyconnection being by'the connecting bars f and the cranks 'n n and m m,the rock-shaft 9 being connected to the rear end of the-tongue by meansof staples.

By this arrangement 1t wlll be seen that the rear end of the tongue, towhich the plows are attached, is free to move up and down, and, bymoving the lever l backward, the cranks M, 'n and m m will be broughtinto line, and as the cranks m m cannot move downward, by

reason of theresistance of theconnecting'bars f, the rear end of the'tongnefwith the plows'l attached, is forced up, thus lifting theplowsout of the ground; but when the lever l is pushed forward, bringing thecranks an and} mtm at right angles, or Jess, the rear end of h when? afl flth eby al ow n h plows to enter the ground.

Thus it will be seen that, the operator be,

ing seated on the frame M, with his feet on the levers d, by them or thelever r, or all together, he can move the 'eenter plows from right toleft at will, or, when walking, can move them
